Port Curtis Tribal communities have joined forces with lobby group Save the Reef to make their concerns public.

Gurang representative and member of the Port Curtis Coral Coast Aboriginal community, Cherissma Blackman, says they met with UNESCO last year to discuss the impact of LNG projects on underwater cultural heritage values.

"What has happened is that has had a huge impact on our cultural heritage sites and the ability for our traditional owners to gather food and hunt respectively within those areas," she says.

She says members of the Port Curtis Coral Coast Native Title Claim Group, which covers the area from Gladstone to Bundaberg, are entitled to compensation but they're yet to see the pay out.

"That's left a lot of our people behind the eight ball in trying to get business development happening, to try and put in for tenders and that, skilling up our people and keeping future generations employed," she says.

She says they're now in the preliminary stages of a class action claim.

"There are serious talks and a lot of information has been handed over," says Ms Blackman.

She says one of the key issues is the lack of access to important cultural heritage sites.

"One of the most important areas for our people along the coastline was the Fisherman's Landing area and The Narrows which is where the pipeline comes through to get to Curtis Island," says Ms Blackman.

She says they no longer have access to those areas.

"The other thing is we have been to these proponents and put forward sustainable partnerships for environmental sustainability," says Ms Blackman.

"But we are not even considered to be a party to have an interest in the joint management for these environmental interests."

Save the Reef's Dr Libby Conners says they're in discussions with the Gurang people about taking additional or joint legal action against the company.

"We're keenly aware of the breeches of the Environment Protection Act in Queensland that has gone on with these rushed developments," she says.

"There's that to be pursued as well as the fact that the value of Indigenous fishing and hunting has not been addressed sufficiently as well as this destruction of cultural heritage which is really hard to put a monetary value on."

She says it's an ongoing issues.

"This has gone on now for a couple of years, I think the Aboriginal community has been incredibly patient and tried avenues of direct discussion both with the gas companies and Gladstone Ports Corporation but several members within the community are saying enough is enough," she says.

She says Indigenous groups have been taken advantage of.

"Aboriginal representatives are often elders who not very highly educated but have a desperate desire to see community development," says Ms Conners.

"They go into these negotiations with these big multi-national corporations with hearts full of goodwill and hope but unfortunately they rarely have legal training.

"So they sign off thinking this is great, it's finally going to bring some community development to our people but then they find out once they sign on the dotted line there might be consultation meetings but they won't get any effective answers from the companies."

Ms Conners says there's been a tragic loss of cultural sites as a result of developments in the area.

"The hill on the south-west part of Curtis Island was a really important signal station in Aboriginal Australia, that of course has been flattened for the first three plants," she says.

"We also know that bora sites were simply bulldozed but it's not of course just the cultural heritage, there is also the issue of the loss of traditional hunting.

"The Aboriginal community has suffered significant loss and they're just being terribly disappointed at the failure of the Indigenous Land Use Agreement to give them any meaningful satisfaction from this process."

She says Indigenous groups are fed up.

"They've just lost too much and have had no gains whatsoever," she says.
